[0020] like Figure 1 , an agricultural product processing production line with an energy-saving system, comprising a pre-treatment section 1, a steaming section 2 and a quick-freezing section 3 through which raw materials sequentially pass;

[0021] The quick freezing part 3 uses a refrigerant to form a cooling cycle for quick freezing. The refrigerant is connected to a cooling tower 11 and is cooled and released in the cooling tower 11. The heat generated is recovered by a heat recovery device 12. The heat recovery device 12 is connected to the heat preservation water tank 4 and is used to heat the water in the heat preservation water tank 4.

[0022] The heat preservation water tank 4 is connected to the liquid inlet end of the electric steam boiler 5 , and the exhaust end of the electric steam boiler 5 is connected to the steaming part 2 .

[0023] In the utility model, agricultural products can be corn, oil-tea fruit, vegetables, fruits, etc., and the production line of the utility model is a quick-frozen packaging and storage line for these agricultural products. The utility model takes corn as an example. Shelled corn is sequentially shelled, cleaned, buffered and heated, steamed, cooled with water at room temperature, air-dried and drained, quickly frozen, packaged, and stored. The corn between two adjacent processes can be transferred manually or automatically by a conveyor belt, a feeder, etc. The pretreatment section 1 is the pretreatment part for shelled corn, such as cleaning and shelling. The steam source of the steaming part 2 is an electric steam boiler 5, and the water source in the steaming part 2 is an insulated water tank 4.

[0024] The steaming part 2 can be a steam warehouse, a steam room, a steam cabinet, a cooking pot and the like, which is provided with a steam inlet and a pressure relief exhaust port, the steam inlet is connected to the exhaust port of the electric steam boiler 5, the steam is introduced, and the exhaust is discharged through the pressure relief exhaust port to stabilize the air pressure. The quick freezing part 3 can be a quick freezing machine, a quick freezing cabinet and the like, which utilizes a compressor, an evaporation pipe, and a condensation part to realize the refrigeration cycle of the refrigerant, and the cooling tower 11 is equivalent to the condensation part. The refrigerant releases heat in the cooling tower 11 and generates heat, and the utility model concept of the utility model is to collect this part of heat for utilization.

[0025] Specifically, the heat released by the refrigerant is recovered by the heat recovery device 12, and this part of the heat is used to heat the water in the insulated water tank 4, so that the water in the insulated water tank 4 is already hot water, for example, about 80°C before entering the electric steam boiler 5, so that the electric steam boiler 5 can generate steam with less power consumption, thereby achieving the purpose of energy saving. Compared with the prior art, the utility model can effectively recover the heat released by the refrigerant and use it in the electric steam boiler 5, can generate steam with less power consumption, fully utilize the heat released by the refrigerant, and achieve more environmentally friendly and energy-saving effects.

[0026] In addition, the heat recovery device 12 is a prior art and can be implemented in at least two ways:

[0027] 1. The heat recovery device 12 is a heat recovery unit. A compressor is arranged in the heat recovery unit to compress the refrigerant. The compression temperature of the refrigerant increases. The water in the insulated water tank 4 enters the heat recovery unit through the hot water circulation pump, and then returns to the insulated water tank 4 after being heated by the high-temperature refrigerant. The temperature of the refrigerant after heating the hot water decreases, and then absorbs the heat released by the refrigerant of the quick-freezing machine, and the temperature increases to complete a cycle. In this way, no medium exchange occurs between the insulated water tank 4 and the heat recovery device 12, only heat is transferred.

[0028] Second, the heat recovery device 12 is a device such as a coil, a heat exchanger, etc., in which the circulating new water is heated and directly enters the thermal insulation water tank 4, generating medium and heat exchange, and mixing and heating the water in the thermal insulation water tank 4.

[0029] Furthermore, a buffer heating section 6 is provided between the pretreatment section 1 and the steaming section 2 , and a normal temperature water cooling section 7 is provided between the steaming section 2 and the quick freezing section 3 .

[0030] The buffer heating part 6 can adopt facilities such as a buffer machine, a buffer warehouse, a buffer pool, etc. Hot water is set inside, and hot water is introduced through pipelines to perform preliminary water bath heating on the corn.

[0031] Furthermore, the normal temperature water cooling part 7 cools down the steamed raw materials with new water, the discharge end of the normal temperature water cooling part 7 is connected to the heat exchanger 8, so that the hot water enters the heat exchanger 8, and the new water output end of the heat exchanger 8 is connected to the buffer heating part 6, so that the new water after heat exchange enters the buffer heating part 6 to provide heat.

[0032] The normal temperature water cooling part 7 can be a cooling pool, a cooling warehouse or other facilities. External fresh water (e.g., tap water) is introduced through a pipeline. The temperature of the corn after steaming is relatively high, and it is beneficial to subsequent quick freezing after being cooled in the normal temperature water cooling part 7. After the normal temperature water cooling part 7 cools the corn by flushing, spraying, soaking or other methods with fresh water, the water temperature rises to form hot water. The hot water enters the heat exchanger 8, and the heat exchanger 8 transfers the heat of the hot water to the water in the buffer heating part 6.

[0033] Furthermore, the discharge end of the steaming part 2 is connected to the heat exchanger 8, so that hot water enters the heat exchanger 8, and the new water output end of the heat exchanger 8 is connected to the cache heating part 6, so that the new water after heat exchange enters the cache heating part 6 to provide heat.

[0034] After the corn is cooked by the steam in the steaming part 2 , condensed hot water is generated, and the hot water also enters the heat exchanger 8 .

[0035] Furthermore, a debris filter 9 is provided at the water inlet end of the heat exchanger 8. The debris filter 9 is prior art.

[0036] In the present invention, the heat exchanger 8 can be one or two, and the two heat exchangers 8 are connected to the steaming part 2 and the normal temperature water cooling part 7 respectively, or one heat exchanger 8 is connected to the steaming part 2 and the normal temperature water cooling part 7 at the same time. A heating pipeline can be set in the heat exchanger 8, which has four ports, namely, a water inlet end, a drainage end, a new water input end, and a new water output end. Among them, the water inlet end of the heat exchanger 8 is connected to the drainage end of the normal temperature water cooling part 7 or the steaming part 2, the drainage end discharges waste water, the new water input end is connected to the external new water (such as tap water), and the new water output end transports hot water to the buffer heating part 6 through the pipeline.

[0037] During the cooking and cooling process, the utility model exchanges heat between the discharged hot water and new water through the heat exchanger 8, recovers the heat in the hot water, and raises the temperature of the new water, for example, to greater than or equal to 40° C., which is used for the buffer heating part 6 to preheat the corn, thereby reducing the heat consumed in heating the corn during cooking, thereby achieving the purpose of energy saving.

[0038] Furthermore, the front end of the quick freezing part 3 is also provided with an air drying and draining part 10. The air drying and draining part 10 can be a drying machine, an air dryer and the like. The corn is dried for quick freezing.

[0039] Furthermore, the pretreatment section 1 includes a shelling part 13 and a cleaning part 14 which are arranged in sequence. The shelling part 13 can be a shelling machine, manual shelling, etc. The cleaning part 14 can be a cleaning machine, spray cleaning, manual cleaning, etc.

[0040] Furthermore, it also includes a packaging part 15 and a storage part 16 arranged at the rear end of the quick freezing part 3. The packaging part 15 can be a packaging machine or a manual packaging method, and the storage part 16 can be a conveyor or a manual transfer method.

[0041] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
